[Bldg-sim] The Building Controls Virtual Test Bed 1.5 has been released.

[Thierry Nouidui]

We are pleased to announce the release of the Building Controls Virtual
Test Bed 1.5.



The following changes have been made compared to version 1.4:



* Added support for FMUs for co-simulation and model exchange for FMI
version 2.0.

* The example files have been updated for EnergyPlus 8.2.



The Building Controls Virtual Test Bed (BCVTB) is a freely available
open-source software environment that allows users to couple different
simulation programs for co-simulation,

and to couple simulation programs with actual hardware. For example,
the BCVTB allows to simulate a building in EnergyPlus and the HVAC and
control system in Modelica,

while exchanging data between the software as they simulate. The BCVTB is
based on the Ptolemy II software environment.

The BCVTB allows users to expand the capabilities of individual programs by
linking them to other programs.

Due to the different programs that may be involved in distributed
simulation, familiarity with configuring programs is essential.



Programs that are linked to the BCVTB are



* the EnergyPlus whole building energy simulation program,

* the Modelica modeling and simulation environment Dymola,

* Functional Mock-up Units (FMU) for co-simulation and model-exchange for
Functional Mock-up Interface (FMI) version 1.0 and 2.0,

* the MATLAB and Simulink tools for scientific computing,

* the Radiance ray-tracing software for lighting analysis,

* the ESP-r integrated building energy modeling program,

* the TRNSYS system simulation program,

* the BACnet stack, which allows exchanging data with BACnet compliant
Building Automation System (BAS),

* the analog/digital interface USB-1208LS from Measurement Computing
Corporation that can be connected to a USB port.



In addition to using programs that are coupled to Ptolemy II, Ptolemy II's
graphical modeling environment can also be used to define models for
control systems, for physical devices,

for communication systems or for post-processing and real-time
visualization.
